Application

1,2-Dimethoxyethane may be used as a solvent in the following processes:
  • Synthesis of cyclic amines from amino alcohols via direct cyclodehydration.
  • Stereoselective synthesis of trans-1,2-disubstituted alkenes from 1-phenyl-1H-tetrazol-5-yl sulfones and aldehydes in the presence of potassium or sodium hexamethyldisilazide.
  • Synthesis of adamantylideneadamantane from 2-adamantanone via reductive coupling.
